The XC6135/36 series are new ultra-low power voltage detectors from Torex Semiconductor that can detect voltages down to as low as 0.5V (XC6135).
Operating voltage for both detectors is from 1.1V to 6.0V and with a quiescent current of only 44nA (XC6135) and 88nA (XC6136) both ICs can extend the operating time of products with small batteries such as energy-harvesting-powered devices, IoT devices, wearable devices, and smart meters.
Typical application functions are expected to include microprocessor logic reset circuitry, system battery life and charge voltage monitors, power-on reset circuits, power failure detection, and so on.
Both the XC6135 & XC6136 feature an operational instability prevention function which stops malfunctions that can be caused by voltage lift under conditions lower than the minimum operating voltage (CMOS output versions only).
The XC6135 also has a sense pin separation function which allows it to detect a high withstand voltage in addition to the factory set detect voltage.
The XC6135/36 are available in SOT-25 & SSOT-24 packages as well as an ultra-compact USPQ-4B05 (1.0 x 1.0 x 0.33mm) package.
